How much oil should be added to an Audi A4?
The Audi A4 requires approximately 4.5 liters of oil, or about 5 bottles if using LDH 5W-40 in quart units. It is recommended to add oil to the middle of the oil尺 range.
In addition to knowing how much oil to add, it is important to understand the role of oil in a vehicle:
1. Lubrication and reducing friction: Oil forms a film between two moving parts to reduce friction and make the engine run smoothly.
2. Cleaning and分散: High-quality oil can absorb and remove small metal debris and flush out particulate matter on the surface of engine components.
3. Cooling and temperature control: Oil absorbs heat as it reaches the moving parts and carries away heat to help cool the engine.
4. Sealing and prevention of leaks: Oil forms a seal between the活塞环 and活塞 to prevent burning废气 from entering the曲轴箱.
5. Corrosion prevention: High-quality oil can protect engine components from air, acid, and harmful gases by covering their surfaces.
In daily life, there are three types of common oil: mineral oil, semi-synthetic oil, and full synthetic oil. Their performance gradually improves.
